For a football game in the National Football League, let y = difference between the number of points scored by the home team and the away team (so y > 0 if the home team wins). Let x bet the predicted difference according to the Las Vegas betting spread. For the 768 NFL games played between 2003 and 2006, output follows.

(a) We wish to test the null hypothesis that the Las Vegas predictions are unbiased. This will correspond with ? = 0 and ? =

b) Based on the results shown in the table, is there much evidence that the sample fit differs from the model ?_y = ? + ?x, with values of alpha and beta above? Why?
